Big flower left by German escort (5)
I believe the answer is:
usher
'escort' is the definition.
(usher is a kind of escort)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for usher that I've seen before include "Doorkeeper, escort" , "Guide at wedding" , "Cinema or wedding official" , "One who shows people to seats" , "Theatre attendant" .)
